Description
E-64 is an Irreversible, potent and highly selective inhibitor of cysteine proteases. It does not affect cysteine residues in other enzymes. E64 acts by forming a thioether bond with the thiol of the active cysteine. E-64 will not inhibit serine proteases (except trypsin) but inhibits activation-induced programmed cell death and restores defective immune responses in HIV. Specific active site titrant.
Applications
• Used as an inhibitor for calpain, papain, and cathepsin B, cathepsin L
• Used to study excystation in Giardia lamblia
• Used to reduce inflammation in cystic fibrosis patients

USE
E-64 is a broad spectrum cysteine proteinase and calpain activation inhibitor. E-64 has been reported to inhibit intracellular cathepsin B, cathepsin L, cathepsin H, Bax protease activity, and reduces oxidative stress, which includes a decrease in MDA levels, ICAM-1 expression and MOP acitivity. Additionally, Prevotella intermedia studies report that E-64 blocks the breakdown of methaemoglobin and the oxidation of oxyhaemoglobin by InpA. E-64 has also been used to study excystation in Giardia lamblia. E-64 is an inhibitor of Calpain, cathepsin K and cathepsin S.
